CIGARETTE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 602,436, dated April19, 1898.

Application filed June 8, 1897. Serial No. 639,821. (No model.)

T0 at whom it may concern.-

Be it known that 1, JOHN O. EATON, a citizen of the United States,residing in Fall River, in the county of Bristol, in the State ofMassachusetts, have invented new and useful Improvements inCigarette-Machines, of which the following is a specification.

This invention relates to cigarette-machines of that class in whichcontinuous cigarettes are made by applying a long or continuouswrapper-strip to a continuous filler,com m only termed a tobacco rod,and folding the opposite edges of the wrapper into engagement with eachother and uniting them by crimping, so as to form a complete seamwithout the use of paste or other adhesive substance.

A cigarette made by this machine forms the subject of an application byme for Letters Patent, filed June 8, 1897, Serial No. 639,822.

In this invention the wrapper-seam of the cigarette is folded andcrimped from the outside that is to say, all the mechanism which foldsand criinps the seam is applied on the outside of the wrapper, and nomechanism or.

tool whatever is applied Within or to the inside of the wrapper or tubecontaining the filler.

In the employment of ordinary continuouscigarette machines in which thecigarette is crimped from both sides-that is, by apply in g mechanism tothe outside of the seam and within the wrapper-the filler often becomesclogged by the inside crimper and mandrel and the paper constituting theseam is very liable to become out. These and other obj ectionablefeatures are done away with by my improved machine, in which a welt-seamis produced providing an excellent lock, whereby the wrapper is unitedat its edges very securely without the aid of paste, the crimpers beingenabled to be made larger and give greaterpressure on account of theirexternal position.

Similar letters of reference indicate corresponding parts. v

A represents a horizontal bed, preferably of metal, supported in and bya suitable base a, which sits upon a table a. Formed in the uppersurface of this bed A is a horizontal groove A, semicircular in shapeand one-half the thickness and circumference of the cigarette which isto be formed therein. This groove extends from one end to the other ofthe bed and is flared at its entrance, as shown at A, Fig. 1.

b is the driving-shaft, supported horizontally in the brackets orhangers a, Fig. 2, and b is a counter-shaft, fast upon which is the gear17, engaged by the gear 1/ on the main shaft 1), Figs. 2 and 5. Fast onthe drivingshaft 1) are the four bevel-gears cl d d d', which engage,respectively, the bevel-teeth e e e e, integral with the gear-wheels ffThe gear-wheel f is fast on the vertical shaft g, which extends upthrough the base a at the left end of the machine, which is the end atwhich the wrapper and tobacco rod enter. On the upper end of the shaft gis a bevel-gear g, Fig. 1, which engages a bevelgear g on the horizontalshaft B, supported by a suitable bracket or standard 13'', bolted to thesurface of the base a. This shaft B drives a disk-wheel B, whoseperiphery is concave in cross-section and which is not thicker than thediameter of the groove or trough A, Figs. 1 and 2. A horizontal guide orshaper O, broad at its rear end and narrowing toward its front end, issustained by the support 0, secured to the surface of the base a, andthe bracket 0, which is secured to and extends rearwardly from thefrontend of the bed A. This guide-trough or shaper has its upper edgefolded inward, as shown, and receives the continuous strip (indicated bybroken lines h in Figs. 1 and 2) from which the wrapper is to be formed.This strip is guided into the machine to be folded and crirnped, ashereinafter described, by the shaper (J, and the tobacco rod is guidedby the disk-wheel B,which is formed with an annular groove for thepurpose of resting on the upper edge of said rod as it is fed into themachine. The shaper C is set at such a height as to guide the strip intothe groove or trough A in the bed, which sits above the surface of thebase a, as shown in the different figures.

The gear-wheel f is fast on a vertical shaft D, which extends up throughthe base, and said gear-wheel engages a similar gear-wheel D, fast onthe vertical shaft D, which also extends up through the base. Rigidlysecured to the upper ends of these shafts are the disk-wheels E and F.These wheels are set horizontally, so as to lie close upon the bed A,and the under portions of their peripheries are grooved atE and F, eachgroove describing an arc of a circle and the two coinpleting the circle,one-half of which is described by the groove or trough A in the bed.(See Fig. 3.) The portion E of the periphery of the wheel E is plain,and the opposite portion F of the periphery of the wheelF is also plain;but this latter wheel is thicker than the wheel E, and its periphery isformed with a horizontal annular extension or lip F, which overlaps theupper surface of the wheel E. When the strip his fed into the machineand reaches the flared end A, Fig. 1, of the trough, the edge g ishigher than the other edge 3 and as the strip is fed between the wheelsE and F the effect of the flange or lip F is to fold the edge 7horizontally over and across the edge 1 into the position indicated inFig. 6.

Mounted upon a support H, just beyond the disk-wheels E F, is avertically-set wheel II, adapted to rotate freely on said support andhaving its periphery beveled, as shown at H. The face of this wheel(which is about one-half the thickness of the tobacco rod) issubstantially over the longitudinal center of the trough A, and aguide-plate I is secured to the bed opposite this wheel and in such aposition that the groove I on its inner edge, Fig. 7, continues thecurve described by the trough A. As the strip proceeds from between thewheels E F to the wheel H and guide I the effect is to turn the edge yof the wrapper, which in Fig. 6 was horizontal, down to the angleindicated in Fig. '7. Next beyond the disk-wheel H and support 11 is aplate J, secured to the bed, such plate being provided with aguiding-lip J, (see Figs. 8, 9, and 11,) the end of which next theapproaching strip is beveled off diagonally at J, so as to cut off thecorner next the approaching strip. As the edge of the lip J faces theinner edge of the plate 1, the effect of this diagonal bevel is to drawor guide the partially-folded edge of the wrapper from the positionindicated in Fig. 7 to the position indicated in Fig. 9, or, in otherwords, to fold said edge y entirelyaround and closely against thenarrower edge y.

The plates I and J are curved or pointed forward at their inner ends, soas to guide the strip between the two horizontal wheels K and L,mounted, respectively, on the vertical shafts .LT and N, the latterbeing provided with the gear-wheel N, which is engaged by the gear-wheelf. The lower portions of the peripheries of these disk-wheels K L aregrooved at K L to fit the cigaretterod, and said wheels lie closely uponor over the bed A in the same manner as the wheels E F. Above the grooveL in the wheel L its periphery is provided with an annular notch orsubstantially rectangular groove L, and the wheel K is provided with aperipheral annular tongue K, which extends into the groove L, all asshown in Fig. 4. As the strip or wrapper is fed from the plates I and Jbetween the wheels K and L the tongue K engages the wrapper just belowthe edge of the flap y, while the sharp projection L, which constitutesthe lower wall of the groove L, extends into the wrapper from theopposite side and doubles it under the part engaged by the tongue K, theupper wall L of the groove folding the two flaps over upon the tongue K,all as indicated in Fig. 10. This leaves the uncriin ped seam aboutevenly arranged on the opposite side of the center of the cigarette oron opposite sides of the point at which the wrapper is folded or formedinto a seam. The next step is to crimp the seam. A bevel gear-wheel Z,Figs. 2 and 5, driven by the counter'shaft 12, engages the bevelgear Zon the inclined shaft P, extending up at an angle through the base a.(See Fig. 5.) A bevel-gear P on said shaft en gagesabevelgear P on anoppositely-inclined shaft P. Fixed on the upper ends of said shafts P Pare the inclined disk-wheels R and S, the lower corners of whoseperipheries are provided with curved grooves R and S to accommodate thetobacco rod and wrapper,

while the upper corners are beveled off at R S to form a horizontalsurface, which is suitably serrated for crimping purposes, Figs. 1, 2,and 5. The bed A is beveled off to allow these wheels to meet over thetrough A.

T'U'are disk-wheels set at opposite inclines and previded with beveledserrated peripha eries T U, adapted to press upon the upper surface ofthe seam, as illustrated in Figs.

12 and 13, when the wrapper containing the rod of tobacco is forced fromthe position indicated in Fig. between the pair of wheels R S and thepair of wheels T U. Thus the seam is crimped on the upper and undersides and the entire crimping mechanism is outside the wrapper andapplied to the outside of the seam. The wheels T U are supported onstuds m, extending from arms m, which are integral with and extend fromthe faces of the gear-wheels a, being secured to the faces of the disksn by bolts 4%, which extend through curved slots 01' in said disks. (SeeFigs. 1, 2, 5, 14:, and 15.) Arms (1 extend up from the disks it overworms q, operated by hand-wheels g. From and integral with the disks itextend the arms 2, which are pivotally supported at t by uprights 15',extending up from the base a. These uprights are adapted by dovetailgrooves and screws 1/ to slide transversely toward and from each otheron slides a, Fig. 1. By means of the dovetail grooves t the uprights tand hence the wheels T and U may be adjusted laterally, and by means ofthe wormgears q a an d the adjustable disks a the relative angles ofsaid wheels T U may be adjusted and changed. In order that the pressureof the crimping wheels T U upon the lower crimping wheels R S may beregulated, springs V have their upper ends secured by suitableset-screws V in the rear ends of the arms 6, and horizontal screws V inthe uprights t" regulate the tension of said springs and hence thepressure of the upper crimpingwheels upon the lower. After thecontinuous cigarette has passed from between the pairs of wheels R S andT U it is guided and drawn out of the machine by the grooved disk-wheel\V on the stud W, Fig. 1, mounted on the standards IV, Fig. 2. This studis driven by a bevel-gear which is engaged by the bevel-gear X, fast onthe upper end of a vertical shaft whose lower end has fast upon it thegear-wheel f. A gear-wheel X is rigid with the grooved disk-wheel IV andengages a gear-wheel X, Fig. 2, mounted on a stud X. Rigid with thisgear-wheel X and exactly under the grooved wheel IV is a similar groovedwheel engaging the under side of the wrapper. Thus the tobacco rod andwrapper are carried through the machine and a Weltseam formed andcrimped by the pairs of disk-wheels E and F, K and L, T and U, and R andS, the latter being fully adjustable and conducted out of the machinewith the seam completed by the grooved wheel WV and a similar onebeneath it, all through the medium of the different connections betweensaid wheels and the driving-shaft b.

In practice the crimping-wheels should be so adjusted that the insideedges will mesh deeper than the outside edges in order to full in theextra amount of paper at that edge. The paper is taken into the machinefrom a suitable reel and the continuous cigarette after leaving themachine passes to the cutting device. Of course all the parts coming incontact with the paper travel at the same rate of speed.
